SHUTTLE-SUPPLYING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 473,377, dated April19, 1 892.

Application filed May 9, 1891.

To all whom it may concern;

Be it known that I, JOHN C. BROOKS, of Paterson, in the county ofPassaic and State of New Jersey, have invented Improvements inShuttle-Supplying Mechanism for Looms, of which the following is aspecification.

My present invention relates to improvements in looms; and the object isto effect the changing of shuttles in a power-loom while it is inmotion, and especially to throw out from the loom the shuttle from whichthe weft has been used and the replacement of a fresh shuttle on theraceway without stopping the loom.

In my patent, No. 371,299, issued October 11, 1887, a number of shuttlesis carried on the lay and a complicated mechanism is used to effect thechanging of shuttles while the loom is in motion. The present invention,however, is designed particularly for weaving silk fabrics.

This invention, which is an improvement on the above patent, obviatesthe objections thereto and provides a simple and effective means foraccomplishing the desired purpose.

With these ends in view the invention consists, primarily, of a drop-boxmechanism arranged and adapted to discharge the emptied shuttle and takea fresh one on one end of the lay only, and -carrying a supply of freshshuttles on a belt supported from the loomframe instead of being on thelay.

My invention consists, further,of details of construction andarrangement of parts, as will be fully pointed out hereinafter.

In the accompanying drawings, Figure 1 is an end elevation of a loomhaving my invention applied thereto. Fig. 2 is a front elevation of theloom with breast-rail, cloth-roller, and cloth partly broken away. Fig.3 is a transverse part-sectional view, on a larger scale, of theshuttle-boxes, shuttle-carrier, and

the various parts associated therewith. Fig.

4 is a part-sectional plan view of the parts shown in Fig.2, and Fig. 5is a similar view of the parts shown in Fig. 3. Fig. 6 is a detailenlarged view of a card and the clips. Fig. 7

is an enlarged view of the shuttle, and Fig. 8 is a detail view of thebracket and binder-finger d 7 Referring to the drawings, in which likeSerial No. 392,286. (No model.)

letters and numerals of reference denote corresponding parts in all thefigures, A designates the frame, in which is jonrnaled the cran k-shaf tA carrying the balance-wheel A, pinion A ,and driving-pulley A, and thebottom shaft A", which carries the gear A meshing with said pinion A Thewarp-roll B, breast-roller B, and cloth-roller B are also journaled inthe frame in their usual relative positions, and the reed B andlay-swords L are also provided, as customary in looms of this character.On the upper portion of the swords is the reed-cap L. The picking-bowlsM are arranged on the lower shaft A to operate the picking-levers M,pivoted on the frame at M and the picking-sticks P, which latter areoperated through the usual connections. The picking-sticks are adaptedto operate the pickers P, arranged to slide on the spindles P P to knockthe shuttle back and forth, and the swords and the mechanism carriedthereby are reciprocated by the connections with the shaft A consistingof the pitman K and cranks K, the said pitman being pivoted at K to thelay.

Having thus generally described the parts of an ordinary loom so far asthey pertain to my invention, I will now proceed to a detaileddescription of my improvements, in which I provide on one end of thelathe b the ordinary shuttle-box but on the opposite end, as shown inthe figures of the drawings, the box is provided with a doubleshuttle-rack ct, which is supported on the forked end N of the rod orbeam N and arranged to be moved vertically by said rod in the slottedframe a (Shown in Fig. 5.) This rod is guided in its vertical movementin the guides N The lower end of this rod N is pivotally connected tothe lever m by the pin N and this lever m is fulcrumed on a pivot-pin m,secured on the bracket m on the main frame. A vertical rod or lever 19is pivotally secured to the outer free end of the lever m by a pin m andthis rod is connected at its upper end to an angle-lever R and anotherlever 13, carrying a hookpawl p Secured on the lower part of the frame,near the bracket m, is an upright bracket 19, on which a levert ispivotally secured by the pin t',and this lever extends rearward below Iand beyond the shaft A in position to be operated by the cam T on shaftA", and it has a slot 6 at its forward end, through which a pin '6 onthe rod 1) projects. By this arrangement the rod 19 is elevated andlowered by its connection with the lever t as the latter is operated bythe cam T, and the slot t provides an easy and free movement.

A slotted angle-bracket Q is secured to the frame A near the forwardupper end thereof, and the angle-lever R, pivotally secured on a bracketR beneath said bracket Q, is arranged to extend upward through the slot,and its vertical part is normally fitted in a notch at one end of theslot. The short arm of this angle-lever R is connected with the uprightrod 1) by a pin K and the longer vertical arm has a projection R on oneside thereof, the function of which will be described hereinafter.

At the.outer end of the slotted bracket Q is a bracket having a forkedupper end, and a similar bracket 7 is secured to the frame A inalignment with said bracket V Journaled in the opposite ends of theseforked brackets W \V are the shafts II, which carry the sprocket-rollerslI II. An endless belt, consisting of a series of plates h", which Icall cards, joined together at their ends by links 7L3, is arranged torun over the rollers ll, and the four angular projections on saidrollers are adapted to engage with the belt where the cards areconnected together. This construction will permit 1 he cards to lie flatacross the face of the sprocket-rollers and move forward as the rollersare operated. On the upper face of each card, near the outer endsthereof, are provided lugs or projections h, in which small clips h arepivotally secured, and springs S are arranged to bear 011 the outersides of these clips to force them toward each other. The shuttles S areinserted between these clips 72 the springs S serving to cause the clipsto grasp them firmly, and the relative sizes of the sprocket-rollers andcards should be proportioned to provide a uniform relation and operationof the respective parts. The pawl p is adapted to engage with one of thecards, as shown in dotted lines in Fig. 3, and as the lever 11 iselevated the pawl pulls the card up and moves the belt and rollersaround the distance of one card.

The shuttles S used in this machine are somewhat different from those ingeneral use, being provided with a tongue carrying a coneshaped collaror block 5, which is forced forward by a coiled spring 6, operatingagainst the shuttle-body. (See Figs. 5 and 7.) This tongue has a buttedend 7, and a dog 8 is arranged on one side thereof, and an inclinedprojection on the butted end 7 is adapted to force the dog or plate 8out against the binder (Z when the tongue is moved forward as the yarnis used up by the spring (5. The spindle it passes through an opening inthe butted end 7 and the collar 5 and receives the cop, said spindlebeing pivoted in the usual manner, as shown in Fig. '7. then the cop isplaced in position in the shuttle, the block or collar impinges againstthe weft, and the spring I) is compressed against the shuttle by theblock or collar. As the weft becomes exhausted, the collar 5 isgradually forced forward by the spring Z), and the butted end 7 andcollar 5 being rigidly connected together said butted end will also moveforward with the collar as the latter is forced forward by the springZ). At the same time the dogS will be forced outward by the inclinedprojection on the butted end 7 to operate the bindertinger d, ashereinafter described.

In the usual construction of shuttle-boxes in series the binders orswells are carried in and with the boxes; but in the construction of thepresent improvements the front of said boxes are left open and thebinders are carried in a stationary box-front I)", secured on thelay-beam b. For the purpose of operating this invention, however, theusual binderswell (Z is slotted to receive an engaging or temporarybinder d, pivotally secured in a horizontal slot at one end therein. Thelooms to which this invention is applied have the usual protector-rod 6,adapted to operate in the ordinary way from the back of the shuttle-box;but as it is necessary to provide for the action of said protector-rodat the front of the shuttle-box I have devised the following improvedarrangement.

Brackets 20 are secured to the lay'beam b, in which a pin 21, carryingthe angular binder-finger (Z is fitted, and the upper end of this fingeris. arranged to bear against the binder-swell (1, while the lower endprojects under the lay-beam from its pivotal point; and is connected tothe lever b on the ordinary protection-rod by a link I). A red n iscarried in brackets 6 fastened to the lay-swords L, and this red has oneach end thereof a binder-finger O. A striker O is also secured to therod n. This finger C is adapted to bear against the temporarybinderswell (l and is held in contact therewith by a coiled spring 6 onsaid rod 11, which is secured at one end to the sword at c and at itsother end to a collar 6 on the rod 92 so that the finger (J is heldagainst the binder-swell (Z. This horizontal projection or striker C isadapted to contact with the projection R on the anglelever R and releaseit from engagement with the notch in the end of the bracket Q, and tocompensate for the blow occasioned by such contact the end of the saidrod 01 is also supported in bracket 20.

The lay-beam 1), adjacent to the bracket Q, is provided with a diagonalslot or recess 22 beneath the binders, through which slot the emptiedshuttle is ejected, and this is accomplished by a feather-shaped leverf, normally pressed forward by a spring j, which is arranged beneath theshuttle-box and projects upward through a slot (1 therein, so that whenthe shuttle-boxes descend, as hereinafter described the lever j,projecting through IOC IIO

the slot, will force the shuttle out of the boX and through the slot orrecess 22.

Having thus described the construction of the several parts of myinvention, the operation thereof may be briefly described as follows:Rotary motion being applied to the crank-shaft A in the usual manner,the pinion A and gear A turn the shaft A and by intermediate strokesgiven to the lever M the picker-stick is actuated in the usual manner byconnections well known in the artand the fly-shuttle is propelled acrossthe laybeam and between the warp-threads. Similar mechanism on theopposite side of the loom returns the shuttle, and the reciprocatingmovement of the shuttle is continued throughout the weaving operation.Rocking motion is imparted to the lay-beam coincident with thereciprocating movement of the shuttle by means of the cranks K,connected to the lay-swords by the pitmen K, the object and result ofthis movement being to beat up each pick of weft in a line to thepreviously-woven cloth. The above stated operations continue until theloom is stopped fora fresh supply of filling in the shuttle in looms ofthe old construction; but when my invention is applied to a loom it isnot necessary to stop it at all, and thusmuch time and annoyance issaved, as the loom automatically supplies itself with fresh shuttles bythe following operations of the several parts: As the filling 4 on thequill or bobbin in the shuttle becomes exhausted, the cone-shaped block5 on the tongue is forced forward by the spring (3 until the incline onthe butted end 7 of the tongue is brought forward sufficiently to forcethe dog 8 out against the binder d. This is done when the filling isalmost, -if not quite, exhausted, and the binder d forces thebinder-finger O outward, thus depressing the horizontal projection orstriker O. As'the lay-beam approaches on the forward stroke, the strikerO is now in such a position that it will engage with the projection R ofthe angle-lever R and release said lever from engagement with the notchin the bracket Q. This allows said lever to pass into the opposite endof the slot in the said bracket, at the same time lowering the rod 19sufficiently to bring the lever m and rod N down far enough, so that theidle-shuttle S, held in readiness in the upper box, will be in alignmentwith the raceway and is driven across the lay-beam by the picker P inthe usual action of the loom. As the shuttle-boxes are lowered, thefeathered lever f, operating in bracket Q, so that the loom willcontinue in action until the filling is again exhausted.

Coincident with the elevation of the shuttle-boxes and rod 19 the lever79, carrying the pawl 19 is raised, and as the pawl engages with thebelt or the cards 77. they will be fed forward until a supplyshuttle iscarriedlnto the position shown in Fig. 1, and as the laybeam againapproaches the front center the grabber S, having the hooked end andpivoted in the rack a, will strike the fresh shuttle as the lay movesforward and move up and over the same until it reaches entirely acrossone side thereof and grasps it firmly by means of its hooked end. Thegrabber is held in a horizontal position by the spring S operating onthe upper side thereof. As the laybeam recedes, the grabber will pullthe shuttle from between the spring-controlled clips -h into its properposition in the upper shuttle-box in readiness to repeat theaforementioned operation of replacing the emptied shuttle. \Vhen theshuttle is removed from the carrier or belt, the springs 8" cause theclips h to fall into a horizontal position on the card 7& and theshuttle is placed between said clips by inserting one end thereof underone clip and raising the opposite clip, so that the other end of theshuttle can be put mp0- sition, and when this is done the clips hold theshuttle firmly between them.

If theshuttle-carrier should become exhausted, the motion of the loomwould be arrested in the ordinary manner by the lever 19 which isarranged to engage with a protectin g frog Y on the frame of the loomand shift the belt back to stop the loom, as is customary.

I am aware that changes in the form and proportion of parts and detailsof construction may be made without departing from the spirit orsacrificing the advantages of my in- I vention, and I therefore reservethe right-to make such changes as fairly fall within the scope of myinvention.

Having thus described my improvements, what I claim as new, and desireto secure by Letters Patent, is 1 1. The combination, with thelay-swords, the lay-beam, and shuttle-boxes of a loom, of the rod N,supporting the shuttle-boxes, the lever m thevertical rod 19, thebracket Q, the anglelever B, engaged in a slot in said bracket andconnected at its short end to the vertical rod p, and means forreleasing said lever B to allow the upper shuttle-box to descend to thelevel of the raceway, substantially as and for the purpose set forth.
